Fix for ddraw: CreateSurface

[Sylvain Petreolle]

Since some surface types are unhandled for now, OffScreenPlain is
assumed.

Unused members of the DDSURFACEDESC2 structure are set to zero,
so the bitperpixel is zero.

DDRAW_width_bpp_to_pitch is called with bpp 0 and apps are stopping on

    assert(bpp != 0); /* keeps happening... */

At least WinDVD starts with this patch, will it be accepted until we
implement other surface types ?
